## Abstract

Chains are passed with a sagging round first sprockets incapable of movement and second and third sprockets capable of movement corresponding to the movement of the opposite free ends of a bellcrank rotatable in a vertical plane. The chains are moved to cause reversal of a billet supported by them. Also, the billet can be clamped by the same apparatus.

## Claims

### Claim 1

A billet reverser comprising a table mounted on a wheeled transporter, a pair of brackets secured to said table, a rotatable shaft horizontally supported by said brackets, an arm substantially horizontally mounted on said rotatable shaft, a rotary housing extending substantially vertically and mounted on said rotatable shaft such that said arm and rotary housing can be rotated about said rotatable shaft in unison with each other like a bellcrank, a stationary housing secured to said table and facing said rotary housing, a first sprocket shaft mounted in an upper portion of said stationary housing and extending parallel to said rotatable shaft, a second sprocket shaft mounted in an upper portion of said rotary housing, a third sprocket shaft mounted in an end portion of said arm, first second and third sprockets fitted on said respective first, second and third sprocket shafts, chain means passed round said first, second and third sprockets with a predetermined sagging, a first reversible oil hydraulic motor coupled to said first sprocket, and a second reversible oil hydraulic motor coupled to said second sprocket, said first and second reversible oil hydraulic motors being coupled to each other by said chain means.

### Claim 2 (depends on 1)

The billet reverser according to claim 1, which further comprises a vice including stationary pawl mounted on said stationary housing and a movable pawl mounted on said rotary housing and substantially at the same level as said stationary pawl.

### Claim 3 (depends on 1, 2)

The billet reverser according to claims 1 or 2, wherein said rotary housing is mounted on said rotatable shaft such that it is not rotatable with respect thereto, while said arm is rotatably mounted on said rotatable shaft, the rear end of said arm and the upper end of said rotary housing being coupled to each other such that the angle between said arm and rotary housing is adjustable.
